I think my preference would be to add a "context" argument to a libdrm
get_hangstats function, but if you feel this way is better, it is fine
with me.

My only [slight, unjustified] concern is that once you make the id
transparent, we can't play any games. Since the DDX doesn't use libdrm
however, I think it is fairly moot.
